C. F. BEVERLY, OF LANCASTER, OHIO.

ROTARY SHINGL-E-MACHINE.

Specification of Letters Patent No. 14,792, dated May 6, 1856.

To aZZ 'whom t may concern:

Be it known that I, C. F. BEVERLY, of Lancaster, in the county of Fairfield and State of Ohio, have invented a. new and Improved Machine for Cutting Shingles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which,

Figure 1, is a side view of my improvement. Fig. 2, is a. transverse vertical section of ditto, X, X, Fig. 1, showing the plane of section. Fig. 3, is a plan or top view of ditto. Fig. 4, is a transverse section of one of the cutters Y, Y, Fig. 1, showing the plane of section. Fig. 5 is a longitudinal section of ditto, Z, Z, Fig. 1, showing the plane of section.

Similar let-ters of reference indicate corresponding` parts in the several figures.

My invention consists in a peculiar manner of attaching cutters to a rotating disk, and also in the peculiar means employed for feeding the block to the cutters, as will be presently shown and described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A, represents a disk or wheel formed of a plate B, firmly secured to arms a, the hub ZJ, of which is attached to a shaft C, which works in suit-able bearings c, c, on a. proper framing or support D. Through the plate B, there is made two oblique openings d, (Z, said openings being in line with each other at opposite sides of the center of the plate. At each end of the openings (Z, CZ, and on the back side of the plate B, there are bars e, e, secured by bolts f, f, and E, E, are knives or cutters which are secured by screws f, to metal plates g, having an ear L, at each end. Through the ends of each knife or cutter near its cutting edge there passes a bolt z'. The heads of these bolts are beveled on two opposite sides, and the heads fit in corresponding shaped or countersunk holes in the ends of the knives or cutters, as clearly shown in Fig. 5. The ears 7L, are attached to the bars e, by screws y', and the proper degree of inclination or bevel is given the knives or cutters by screws k which pass through the bars e, at their upper and lower ends, two through each bar, see Fig. 4. One end of the knives or cutters project farther out from the disk or wheel A, than the other end, the inner end of one knife or cutter and the outer end of the other, as shown clearly in Fig. 3.

F, represents a` plat-form or bed attached to the framing or support D, at one side and near the face side of the disk or wheel A. At each end of the platform or bed F, there is affixed a slotted rail G, in which rods Z, Z, tit and work, said rods fitting in the end of a bar I-I, which works upon the platform or bed. The outer ends of the rods Z, Z, fit in slotted plates I, I, which are attached to the upper ends of bars J, J, the lower ends of said bars being attached to a rock shaft K, on the lower part of the framing D.

L is a treadle attached to the rock shaft K. The inner end of this treadle bears against a semi-cylindrical projection m, attached to the under side of a semi-elliptic spring M, attached to the framing D.

The bars J, J, are made sufficiently thin that they may be somewhat elastic and the ends of the cutting edges of the knives or cutters are beveled, as shown at a, Figs. 1 and 3.

The operation is as follows: The block of wood, shown in red, from which the shingles are cut, is placed upon the platform or bed F, between the plate B and bar II, the bar in consequence of the spring M, keeping the block against the face of the plate B. The disk or wheel A, is rotated in any proper manne-r and the knives or cutters E, E, cut the shingles from the block as they pass it, the required taper being given the shingles, by adjusting the knives or cutters, as previously explained the butts and points of the shingles being cut alternately from'each end of the block, and the block being kept properly adjusted to the cutters at each cut, by the elasticity of the bars J, J, and the spring M, the bar H, being allowed to turn in oblique positions in consequence lof the rods Z, working in the slotted rails Gr, G. The beveled ends a, of the knives prevent the knives or cutters from following the grain of the wood or being deflected from their proper course in cutting the shingles, as said beveled ends will bear against the inner ends of the slotted rails G, G. By having the bolts z', z', pass through the ends of the knives near their cutting edges, the cutting edges are strained perfectly taut.

I do not claim the knives or cutters E, E,

secured to the Wheel A, as shown, irrespective of the manner of attaching said knives or cutters t0 the Wheel, but

Having thus described my invention, what I claim as new and desire to secure by'Letters Patent, is,

l. Securing the knives or cutters E, E, to the Wheel or disk A, by means of the bolts z', z', which pass through the knives or cutters near their cutting edges and through the ears h, at the ends of the plates g, the heads of said bolts being beveled, and ernploying the screws j, for securing the ears to the bars e, attached to the Wheel or disk and adjusting the knives or cutters by nieans of the screws 7c, c, Which pass as set forth.
